The actin related protein 2/3 complex, subunit 3, 21kDa ELISA kits listed below are analytical tools for measuring concentrations of actin related protein 2/3 complex, subunit 3, 21kDa in various samples. actin related protein 2/3 complex, subunit 3, 21kDa is an alternative name for the human ARPC3 gene, which encodes the protein, actin related protein 2/3 complex subunit 3. The target protein is a known component of the Arp2/3 complex, a multiprotein complex that mediates actin polymerization upon stimulation by nucleation-promoting factor (NPF). Structurally, the ARPC3 protein is described to be 178 amino acid residues in length and 20.5 kilodaltons in mass. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include ARC21, p21-Arc, and actin-related protein 2/3 complex subunit 3.
